Monitoring your body hydration is the key to maintaining good health. New, non-invasive instruments make it possible for people of all ages to scientifically take over monitoring their hydration level. The implications are staggering: improved physical performance; improved health; improved longevity; the reduced incidence of disease; and lower health care costs. The inventor of the notebook computer takes us on his next challenge: creating a device that accurately detects hydration levels (through a simple breath sample) to identify when and how to create maximum body hydration. Chris Gintz is the inventor of the notebook computer and other complex instruments. His newest invention, called the hydration measurement instrument, is a microwave rotational spectrometer for the scientific measurement of hydration that anyone aged 3-100 may use. His new instrument methods make it possible for people of all ages to scientifically take over monitoring their hydration level. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
